CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 453,978, dated June 9,1891.

Application filed February 26 1891- To all whom it may concern:

Be it known that I, ELIAS FRANTZ, of Allentown, in the county of Lehighand State of Pennsylvania, have invented certain new and usefulImprovements in Oar-Couplings, of which the following is aspecification.

The present invention consists in improvements applicable to existingrailway-cars having pin-and-link couplings, whereby the same arerendered automatic in coupling, and may be uncoupled withoutnecessitating a trainman passing between adjacent cars.

The present improvements are illustrated in the accompanying drawings,wherein- Figure 1 shows in longitudinal vertical section two adjacentdraw-heads, the couplingpin of one being shown elevated and that of theother lowered; and Fig. 2 shows a plan view of one of the draw-heads.

In the drawings, A A are chambered drawheads of two adjacent andapproaching railway-cars.

B B are the coupling pins thereof, and C is a coupling-link.

Each pin B is pivotally connected at its upper end to the front end of abar D, the rear end of which is pivoted to a stationary verticalbraoketE, fixed to the draw-head. When the bar D is raised, the pin B is out ofconnection with the link 0, and when lowered the pin enters the link andso couples the cars. The bar D is maintained in its elevated position bya toggle-joint, the upper member F of which is pivoted to the bar D, andthe lower member G of which ispivoted at a to the draw-head or a fixedpart thereof. The two members F G of the toggle-joint are connected by aknuckle-joint b. By bending or breaking the joint between the two togglemembers F G, the bar D, and with it the coup- This' is automaticallyeffected by the entrance of the coupling-link 0 into the draw-head,having its coupling-pin elevated- The lower toggle member G constitutesin itself a lever, since it is provided with a downwardly-extendingextension or tail 11 below its pivot. To this extension is pivoted andsuspended by a knuckle-joint c a pawl I. This pawl I is free at alltimes to Serial No. 382,945- (No model.)

swing forward on its pivot, but cannot swing on its pivot backwardbeyond a vertical plane when the bar D is raised. When the coupling-link O enters the d raw-head, it encounters the pawl I, which isthen located within the chamber of the draw-head, thus forcing the pawlI and the lower toggle member 0 to swing backward on the pivot 01,, andconsequently breaking the joint between the tWo toggle members andallowing the couplingpin to drop into the link. In order to uncouple it,it is only necessary to lift the bar D. This can conveniently be done bya bail J, extending beneaththe bar D, said bail being carried by arotary shaft K, extending to the sides of the car and havingoperatinghandles L. If when the uncoupling is effected the pawl I comesin front of the end of the link, it will not interfere with the withdrawal of the link, since the pawl will swing forward out of the way.

. I claim as my invention.

1. In a car-coupling, in combination with the draw-head, the bar D,pivoted thereto, and at its front end the coupling-pin, and toggle-jointF G, pivoted at opposite ends to the said bar D and described.

2. In a car-coupling, in combination, the draw-head, bar D, toggle-jointF G, pivoted at opposite ends to the said bar and draw=head, and theswinging pawl I, connected to the said toggle-joint and adapted to beengaged by the coupling-link to trip the coupling-pin, substantially asdescribed.

3. In a car-coupling, in combination with the bar D, pivoted to thedraw-head, having the coupling-pin pivoted thereto, and togglejointcomposed of the members F G H, the bail J extending beneath the bar D,and having crank-shaft K L, substantially as described.

4:. A chambered draw-head, a coupling-pin, a bar pivoted at oppositeends to said drawhead and pin, and a toggle-joint consisting of twomembers connected together by a knuckle-joint, the upper of said togglemembers being pivoted to said bar, and the lower of said toggle membersbeing pivoted to the draw-head, substantially as draw-head and having aportion extending In witness whereof I have'hereunto signed below saidpivot, in combination with a pawl my name in the presence of twosubscribing connected by a knuckleoint to said downwitnesses.
